Security review of YANG Module for IS-IS Reverse Metric draft-ietf-lsr-yang-isis-reverse-metric-04 Do not be alarmed. I generated this review of this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving security requirements and considerations in IETF drafts. Comments not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. The abstract (with typo noted): This document defines a YANG module for managing the reverse metric extension to the Intermediate System to Intermediate System intra- domain routeing information exchange protocol (IS-IS). ^ The spelling error seems to have been copied from ISO Standard 10589:2002. There's no need to continue propagating it. The draft has a decent discussion of security considerations regarding the privacy of the information expressed in the data. The document is READY. Hilarie
